NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent'No. 761,661, dated June '7,1904.

Application filed March 12, 1904.

' vice that is adapted to be molded into the neck of a bottle'for thepurpose of preventing the refilling of a bottle after-its originalcontents have been dispensed.

..With this briefly-stated object in view my invention comprises abottle having a valveseat adjacent the lower end of its neck againstwhich operates a disk valve which is normally held adjacent to thevalve-seat by a plug that is inserted and held into the lower-end of thebottle-neck, said plug having a recess in its lower end 'into'which thevalve opens and a zigzag passage through which .the contents of thebottle escape when the valve is open,

and in order to avoid any possibility of the valve obstructing theescape of the liquid I propose to enlarge the lower end ofthe bottleupon one side, said enlargement forming practically a continuation ofthe zigzag passage.

My invention also comprises certain details of construction andnovelties of combination and arrangement, as will be fully described inthe following specification and pointed out in the claims, referencebeinghadto the drawings, in which Figure 1 is a perspective view of abottle embodying my improvement. Fig. 2 is a vertical sectional viewdrawn through the neck of a bottle with my improvement in place.

Fig. 3 is a similarviewshowing the bottle tilted, the location of thevalve, and the escape of the-liquid. Fig. 4 is ahorizontal sectionalview drawn on about the line 4: 4: of Fig. 2. Fig. 5 is a verticalsection of the plug, said section being taken in the line 5 5 of Fig. 2.Fig. 6 is a detail perspective view of the plug, and Fig. 7 is a detailperspective view of the valve.

In the practical application of my invention $erial No 197,790- (Nomodel.)

I may employ any suitable form or shape of bottle A, having an elongatedneck A, and upon one side of the neck near its base I provide anenlargement A which is recessed or concaved upon its inner side, thepurpose of which will appear hereinafter. A valve-scat A is arrangedwithin the bottle at the base of the neck and surrounds an opening A.The

upper face of the seat is ground to provide a perfectly flat seat.

Within the lower end of the neck of the bottle I arrange a plug B,havinga zigzag assa e-wa B extendin throu hout nearl B c b C! y its entirelength and a recess B in itsextreme lower end. This recess is circularin shape, and its upper wall is preferably arranged upon an incline, asshown at B One side of the plug is cut out, as shown at B and thiscut-out portion is arranged. opposite the enlarged portion A of the neckof the bottle, so

that a continuous passage-way is provided between the upper and lowerends of the plug, and it will be noticed, particularly by reference toFig. 2 of the drawings, that one of the partitions B that forms thezigzag passage-way of the plug has its outer edge terminating onalinewith the concavity of the enlargement of the neck. .The zigzagpassage-way also extends entirely through the plug at diametricallyopposite points for the purpose of permitting the neck of the bottle tobe pressed slightly into the plug, as shown at C, which will prevent thewithdrawal of the plug after it has been arranged in position, and itmay be said here that of course these inwardly-extending portions C maybe made while thebottle is still hot, or they may be provided for in themolding ofthe bottle. A disk valve D is arranged within the recess B ofthe plug and. has its lower face ground to provide a smoothbearingsurface which is adapted to set smoothly and tightly upon thevalve-seat. Two or more perforations D are understood that the bottle isnot always tilted to the position shown in Fig. 3 of the drawings; butwhen tilted in the opposite direction the valve attains a positionopposite to that shown in the drawings, nor will the perforations alwaysbe in the position shown, as the valve will undoubtedly revolve; but nomatter in what position the valve maybe or the bottle tilted theperforations will permit a certain amount of air to enter the bottle. Inmolding the plug in a bottle the valve is placed within the recess ofthe plug and held against the upper wall by means of a wire or tape E,which is of course previously arranged throughout the zigzag passage andits lower end bent over the edge of the valve, as shown at E, whichfirmly holds the valve in place. The opposite endot' the wire or tape isconnected to a ring E, by which the wire or tape may be withdrawn afterthe bottle has been thoroughly cooled, and of course it will beunderstood that this wire or tape is made of sufficiently flexiblematerial to permit this operation and that it is not withdrawn untilafter the bottle has been filled, when the valve will readily drop toits seat.

It will thus be seen that I provide an exceedingly simple, cheap, andhighly-eflieient device that contains but few parts, and there- .l OIiOrendering it impossible of getting out of orc er.

Having thus fully described my invention,

what 1 claim, and desire to secure by Letters Patent, is-

1. A device of the kind described, the combination of a bottle having anenlarged portion formed upon one side of its neck providing a concavitywithin the neck, a valve-seat arranged at the lower end of the neck,said valve-seat having an opening arranged therein, a plug arranged inthe lower end of the bottle-neck, said plug having a zigzag passagewayarranged therein nearly throughout its entire length and a recessarranged in its lower end, the said plug also having a portion of itsperiphery cut out, said cut-out portion being arranged opposite theconcavity ol' the neck w of the bottle, and a valve arranged within therecess of the plug adapted for engagement with the valve-seat, saidvalve being peri'orated near its periphery, all For the purposespecified.

2. In a device of the kind descrihed,the combination of a bottle havinga valve-seat arranged at the base of its neck and an opening arrangedtherein, a plug arranged within the neck and havinga zigzag passage-waytherein, said passage-way extending to the periphery of the plug atdiametrically opposite points, depressions formed in the neck andextending into the said passage-way, the said plug also having a recessin its lower end which communicates with the said zigzag opening, and avalve arranged within the recess and adapted .to rest upon thevalve-seat, as specified.

3. Ilnadeviceoi the kind deserihed,theeon]- bination of a bottle havingan enlarged portion formed upon one side oi its neck providing aconcavity inside the neck, a valve-seat arranged in the lower end of theneck and having an opening produced therein, a plug arranged within theneck, said plug having a zigzag passage-way produced therei n and arecess formed in its lower end, the upper wall of the recess being thepartition between the zigzag passage-way and the recess, the said wallbeing arranged upon an incline, one side of the plug having a cut-outportion alining with the said concavity ol the neck, one o!' thepartitions forming the zigzag passageway in the plug terminating on aline with the concavity of the neck and a disk valve operating withinthe recess of the plug and adapted tor engagement with the valve-seat,all substantially as and for the purpose specified.
